That will not necessarily scale, and I wouldn't recommend it - your "backup
node" will need as much disk space as an entire replica of the cluster
data. For a cluster with a couple of nodes that may be OK, for dozens of
nodes, probably not. You also lose the ability to restore individual nodes

There is another way. You create a cassandra node in it's own datacentre,
then any changes going to the main cluster will be replicated to this node.
You can backup from this node. In the event of a disaster the data from

There isn’t a lot of “actual documentation” on the act of backing up, but I did
research for my own company into the act of backing up and unfortunately,
you’re not going to have a similar setup as Oracle. There are reasons for

The doc for backing up – and restoring – Cassandra is here:

snapshot is the starting point for backing up Cassandra.

Hi Maria,
It depends which backup software and hardware you plan to use. Do you
store your data on DAS or SAN?
Some hints regarding Cassandra is either to drain the node to backup or
take a Cassandra snapshot and then to backup this snapshot.
We backup our data on tape but we also store our data
